r800x Sony Ericsson boot loop

So I got my bootloader unlocked and it seems that every single kernel I try does not work. I've tried the cdma kernel for cyanogen and it doesn't boot (the update.zip doesn't flash in clockwork either... it gives some error and aborts in the middle of it.)
the closest i've got to working is using the doom kernel v3 and that gets stuck in a Sony Ericsson bootloop. if it matters i used it with zerorom v4.
i have a rom that i can boot from to get into clockwork that i got from Alejandrissimo when he unlocked my bootloader. what can i do? I know that i can use flashtool to flash back to stock, but i wouldn't be here if that's what i really wanted. I want a rooted custom kernel and a custom rom, but I can't seem to find any that work for me. any ideas? clearly i'm doing something wrong since other people seem to not have this problem.

Anything yet?
I've been having the same problem, and have had NO luck finding a solution. No matter what kernel/rom I try, I ALWAYS get the 'Sony Ericsson bootloop'. This is getting incredibly frustrating!

First, have you make sure to wipe dalvik/system/factory restore using Team Win Recovery Project or Clockwork Mod? I found that I was bootlooping because I had missed that step. If that doesn't work, you can always resort to flashing on the stock firmware. It won't relock your bootloader, so you can retry the rom/kernel once you get it up and running again. Hope that helps!

It doesnt matter what you do. Cm does not support CDMA xperia play.

I've made sure to do all the proper data wipes. I've tweaked many devices before and for some reason, this phone is the most difficult one to work with. After the 6th factory fw flash, I'm throwing in the towel for the time being. Thanks for the help though. I really hope a solution can come for this. Judging by the amount of views for this thread, it doesn't seem like an isolated problem.

Have you tried to go into recovery after flashing the kernel?...I used paxs cm10 it booted fine.

After flashing the kernel, I can. As soon as I load the rom and reboot though, the bootloop starts. At that point, I can't get it to boot into recovery anymore.

What ROM are you trying out...& what kernel... Also what model# do you have (r800x/i/a/at)...how are you flashing by the way... Cmd or flashtool?...just trying to find out as much as I can in order to help where I can.

r800x (Verizon). I'll have to get back to you on the specific roms/kernels as I'm not currently on the computer holding them, but it's been 4 different ones of each (2 ics based and 2 jb based). I've tried different combinations of the compatible roms/kernels, and I've been using cmd/fastboot for the kernel flashing.

you do have your bootloader unlocked right...

Yes.

& what command are you fastbooting with...I know it seems like we are playing 20 ?'s but I've only ran into that problem when I loaded the temp recovery... If you flashed any Jb ROM its important to format system before you flash the ROM. Might also be needed on certain ics roms.

[Q] Stuck on boot loop

I tried a search but didn't find much of any relevance to my Arc's problem.
My Arc was getting quite laggy so I decided to wipe and put a custom ROM on. I rooted, then unlocked the bootloader and managed to put on CWM using DoomLord's kernel. Everything fine up until here.
Then, mistakenly, I tried to put stable CM7 on without updating the stock ROM. I was still on 3.0 (2.3.3) something. Well, after that it got stuck in a boot loop with the SE and CM7 logos just coming up and restarting.
I then tried the Flashtool with a stock uptodate 4.0 something firmware. It flashed successfully, but it still was stuck in the loop, albeit now without the CM7 logo. I then tried the FTA unbricking tool for repairing the trim area but it still stayed in the boot loop.
What else can I do? Maybe there is a driver problem and that is why even after using Flashtool it still doesn't boot?
I would be very grateful if someone could help me on this.

You have to flash FXP's kernel and not DooMKernel.

But I also tried to flash a stock rom and that didn't work also.
EDIT: I flashed stock ROM again, still didn't boot. Installed DoomLord kernel and then arconium and it still doesn't boot.
EDIT 2: In CWM Recovery if I try to wipe data, it says this:
"E:format_volume: no MTD partition "userdata"
Has anyone got a fix for this?
It would be much appreciated.

can you charge your phone now?

Yep, I can charge the phone.

it means your kernel is still working....
then have it fully charged, then try to flashing again.
some tips:
1. always have latest flashtools
2. always have your phone fully charged b4 flashing.
3. proceed flashing carefully. if u miss one thing, then trouble come.
4. have cache and dalvik cache cleaned after flashing a kernel or Rom.
good luck mate...

No luck with previous firmwares so I'll try to flash the latest .62 stock ROM and then see.
I'll let you know how I get on. Thanks!

Well lads, I managed to get it working by flashing the LT18i firmware (4.0.2.A.0.42_CE). Now I just need to go back to the drawing board and try to get CM7 on there.
Thanks for all the help! I'll update this thread with any experiences.

I've managed to do it. Installed latest .62 firmware, flashed CM7 kernel, flashed 7.2 ROM and then GAPPS.
I don't know why it took me two days to bring the phone back from the dead.

hi, i came up with the same question:
E:format_volume: no MTD partition "userdata"
and my device is moto xt502
could you be so kind to give some details how you fix it
thank you very much

I am having the same problem too..please help! i flashed cm7 kernel n followed the instructions very carefully

I followed the instructions too, though they are not so much noob-friendly (and neither are the people on the forums, it seems...). FXP is not responding (actually, they rarely respond to anything, they usually just post when new release is out), other people either don't know how to fix it, because they haven't experienced such issues, or they are just hostile because you're "a an annoying noob". Anyway... first time after trying to flash 64 baseband on 107 or 106 release, I got stuck on logo, then flashed back to .42 and it worked. Now, while updating to 108, I tried to flash the 64 libraries and patch, but it didn't work. Got back to .42, but this time nothing happened. Still stuck on logo. And when I try to restore data, it says:
E:format_volume: no MTD partition "userdata"
Error while formatting /data!
I think I'll go back to stock... love CM, but hate the poor/no help of the developers...

try these
flash new firmware using flashtool.
after flash.turn on your device.
enable uknown source n usb debug
then turn off your fon
flash baseband 64
then turn on your fon
put fxp108 updated-kang,gaps,baseband 64 libs on your memory card,
then turn off your fon
flash fxp kernel fastboot flash boot boot.img
after flash turn on your fon..go to recovery
formated factory reset,wipe cache,clear dalvik cache,wipe betry stats..
flash update cm7.update.zip,gaps.zip,baseband64libs.zip
reboot your fon..wait 2 or 3 mint..done

My thanks goes to you. I was hoping to avoid full wipe, but I don't care anymore, since I brought my phone back to life. I skipped these steps, though:

...because I went to check which baseband my phone was after flashing Global .62, and it said I was on -64, so it was no more necessary. For all of you having trouble with booting, follow the instructions given.
And now back to restoring all those apps

hey guys, can you post the link to that stock firmware, baseband and libs? maybe I've downloaded something wrong :/
btw. is there still that bug with a dark screen after locking phone?

This is the link to the stock 4.0.2.A.0.42.. flash it using flashtool.. http://www.multiupload.com/W3B7BOKUXQ
Everything you need for flashing FXP is on his signature, including bb .64 (to be flashed with flashtool - doesn't erase a thing).. then download FXP (latest is 108) and inside the zip file you'll see boot.img, which contains the special kernel (to be flashed using fastboot, not flashtool).
Also there's no dark screen bug in the latest releases, certainly not in FXP 107 and 108, which I'm using now.

Please help!

Hey, this is my first post on here. I am new to android and just got an arc a few days ago. Even before i got it i was trying to figure out how to mod it. I am reasonably good at computers but a lot of the stuff i read on these forums is beyond me.
I have done my best to root and install CM7 on my arc but i have failed yet again.
I finally got it rooted and was all happy until when i tried to install CM7, all i can get to is the boot screen, but although the little android on the skateboard is very cool, i wish i could get it going!
So because I dont really understand the list of instructions you posted in this quote, i was hoping you could kind of translate into noob-speak. I still dont feel like i completely understand 'flashing'. In your instructions you say to "flash baseband 64" and that is the main point where I am stuck i think. Do you use a certain program (flashtool?) for this? or do it through a terminal window on the PC.
Also links to all the files mentioned would be awesome, its hard to find proper links with multiupload down and that kind of thing. Also with the rate this kind of tech evolves, things get outdated to quickly.
Please help! At the moment i have (i think) successfully returned my arc to the stock firmware using flashtool. Although i did this twice because i re-tried flashing CM7 and failed again. And the second time i couldnt seem to select LTI5i as the device to flash too, but LTI8i is what i used and it appears to have worked. So any help with that little conundrum would also be appreciated!
Cheers for any help given, I am so desperate to get this mod going as i have spent a solid 10+ hours trying already.

your bootloader unlock?right?
which kernel u use right now?

@tehknowitallnoob, I can lead you through the whole flashing process, if you want to, but only on Friday after around 9 pm GMT +1, since I don't have the time to do it earlier.
Sent from my LT15i (Xperia arc) on CM7

Try this:
Reflash back to stock ROM with a flashtool.
Then again flash the cm7 or try cm9

[Help] Custom ROM

I updated my Arc S with the official ICS update from sony however the lag and other issues were driving me mad so i decided to root my phone.
The next obvious step seemed to be installing a custom ROM so i installed clockwork mod and made a back up, everything great so far.
I made a back-up and wiped my phone, went to install the free xperia CM9 ROM and thats when everything went pear shaped.
The ROM didn't install, i wiped my phone again but got the same distressing fail.
Thinking there was possibly a fault with the zip i re-downloaded the ROM and found an alternative (one of the arcronium ones i think) and put those on my SD, all seemed to be well and good, i had a backup and Clockwork Mod what could possibly go wrong?
Well when i tried to boot my phone in recovery all i get is a boot loop! :crying:
The only thing i could do was to use flashtools and flash a ROM to my beloved Arc S
I tried this exact process a few times but suffered the same fate, please can someone tell me what I'm doing wrong? or could i apply a custom ROM using flashtools?
Where I'm currently at:
Model number: LT18i
Android version: 4.0.3
Baseband: 8x55A-AAABQOAZM-203028G-70
Kernel Version: 2.6.32.9-perf [email protected] #1
Build Number: 4.1.A.0.562
Where I would like to be in an ideal world:
Fully working Arc S running Cynogen Mod 9 :victory:
Any help achieving this would be greatly appreciated!

FXP ROM function best on FXP Kernels... Try flashing one of their Kernels and reinstalling the ROM.

Bootloader open?
And for CM u need a fxp kernel, but u cant use it with arconium, there u need trinity or arc-knight kernel

Make sure to do a "Wipe data / factory reset" and "Wipe cache partition" when going from stock or from another custom ROM

I have no idea if my bootloader is open or not, how do i tell?
I found this link to the FXP CM 9.0 but i have no idea what anything is.
http://forum.xda-developers.com/showthread.php?t=1356685
I'm guesing "CM9.0 RC1 FXP127" is a kernel? and if so how do i flash it and what do i do next?
Thanks for the replies, I'll be getting my Arc fixed in no time

Did you follow any instructions from sony to unlock bootloader?

No, it's a ROM. You need to read things carefully before just going and flashing this or flashing that. Flash a stock ROM with the Flashtool and start over.

Dude, First thing you gotta do is unlock your boot loader. Google around you will find it. To unlock the boot loader as well as to flash a custom kernel you need something called fastboot. There is a video in youtube on how to use fastboot and flash custom kernel and that user has provided the download link as well go and search. After unlocking boot loader install CWM (either with auto installer or by flashing a custom kernel with CWM) After doing that flash the FXP127 zip booting in to CWM. The FXP127 zip contains the FXP kernel as well so don't worry when you flash that the kernel gets changed as well. Still can't figure it out. I suggest you keep away from flashing roms Just kidding.

I'm on a stock ROM at the moment that i flashed so i'll just follow some instructions and unlock my bootloader first.
Where can i the latest FXP kernel?
Again Cheers guys

You can find CM9 kernel in zip that you just downloaded. Open it an Extract "boot.img" file. That is the kernel. Flash that first, go to recovery, wipe all data, wipe dalviks chcae, format /system and then chose "install .zip from SD card" and select FXPCM9.zip (or whatever it is named) and it will install you CM9. Don't forget on Gapps.

excellent i unlocked my bootloader and i've got the kernel and rom i want, just one last thing, whats the baseband and when do i flash it (if i have to flash it at all)?
Unfortunately i forgot i uninstalled the stock sony launcher and when unlocking the bootloader it wiped launcher pro so my phones pretty useless as it stands so the quicker i can get a new rom on the better!
Many thanks again, I'm slowly getting there

All done
Cheers for the help everyone!

baseband controls radio communications like communications with cell towers

I did not flash any baseband and it works

NEED HELP with Xperia Arc/ Arc s flashing

Ok, so basically i have just gone ahead and followed these steps for flashing cyanogenmod:
wiki.cyanogenmod.com/wiki/Sony_Ericsson_Xperia_Arc:_Full_Update_Guide
When i got up to step 7, i wasn't able to load clockwork mod, and because i am a noob and new to this, i actually didn't know that i had to install it beforehand. So now, i've got a phone which wont turn on properly (stuck with a lit up black screen) and will only connect into fastboot
Please, somebody help me!!!! I am really scared that i may have bricked my phone, if i can do anything to get it running again, i would be so happy. Please help

did you flash the CM kernel? and CM recovery comes with the kernel..you dont need to install it separately..

Alright first thing first. Which version of CM are you trying to flash? And where you downloaded it from?
---------- Post added at 04:15 AM ---------- Previous post was at 04:06 AM ----------
Ok we will come to flashing ROMs later lets first get you to boot your phone so that you can use it and not be scared. Whatever you have messed up, flashing the phone with flashtool and official FTF would make it normal. I hope you know how to do it. Google around and you can find flashtool. Get it installed to you PC then go here http://forum.xda-developers.com/showthread.php?t=1330314 and download the ftf file and flash it using flashtool. Then your phone will be back up and running. Once its done. Come back here and tell me. Ill help you with flashing ROMs.

@ arpith.fbi
Yes i flashed a boot.img that came with the CM9 zip file, but that is all.
@ gnirujan
I am flashing CM9, and i got it from the downlaods section of the CM website.
I have also downlaoded flashtool but im not sure how to flash the FTF file. By the way, that file is for LT18i, and i have a LT18a. Would it matter?
Thanks for the replies

also gnirujan,
I checked that FTF file, and its 370mb. Is it the full firmware? If it is, i will flash it but if there is a way to continue with the cyanogen flashing, i would love to avoid downloading that ftf.
P.S. LANKAN PRIDEEE!!!!

ok first tell me during startup do u see boot logo? or any logo?

When i boot up, all i see is a lit up black screen with nothing on it

Flash the attached boot.img which is the FXP CM9 kernel from this site, then install the zip.

Ok, thanks, i will try it.

That didn't work either , did the same thing as the other.

I have managed to flash a stock ics ftf file, and i have finally rooted my phone. Now i want to try Rom manager instead to install, but when i go to install Clockwork mod recovery, it says stuff about my phone not currently being officially supported.
Any ideas?

Your boot loader is unlocked right? You wanna install Cynogenmod 9 right? You dont install the one from cyanogenmod site. It has a non working kernel. In XDA there are these guys called FXP (Free Xperia Project) they are the ones responsible for CM for all Xperia devices. So do this. Go tho this thread http://forum.xda-developers.com/showthread.php?t=1356685 download the CM9 RC 1 FXP 128. Its a 130MB file. Download it and now extract it and flash that boot.img to your Arc S using fastboot. Now start your phone and you should see FXP boot screen then from there go to recovery and try flashing the CM9 RC 1 you have. That should work. I suggest if you can replace the CM9 you have in your memory cad with the FXP128 zip its better so that you can flash the latest FXP128 CM 9, which has lots of improvements.
Edit: Arc S and Arc same ZIP its called anzu

Allright as far as i know there are two ways you can get CMW installed on your phone. 1. Download CWM auto installer from play store and install CMW through that. 2. Flash a kernel which has CWM pre installed.
In this link http://forum.xda-developers.com/showthread.php?t=1680793 you can find stock sony kernel with CWM. You download it and flash it using fastboot. That will get you CWM. hope i helped you.

Thanks gnirujan,
I managed to find a FXP127 kernel yesterday and it worked. But this would be even better. I heard that FXP128 is much faster as well, but I've already set up my whole system and dont want to reset it now . Any way of updating it without wiping?
Thanks again !!!

I believe you can try flashing on top of your existing system. I personally have never tried it. But i think it is possible. I would recommend you to flash FXP 128. The improvements are very very visible. More fast and smooth.

[q] my xperia play is stuck on bootloader after flashing kernels

Guys i really need help, I'm using an xperia play and i had just unlocked the bootloader and then flashed a the trueancestors ics rom and the LuPuS_zeus_Stock-gB+iCsv7-full kernel. Now it turns out that i didnt like the rom so i put it back to stock, still with the lupus kernel. Everything was working however i wanted to have the doomkernel v14. So i flashed the doomkernel and it was working however the wifi had erroros so i changed back to the lupus kernel. Again everything was working fine now. I then found out how to fix the wifi problem on doomkernelv14 so refrlashed that kernel. Before i reflashed the kernel i deleted the trueancestors isc rom as i didnt like it so i thought it would be ok. After the flash i tried to reboot the device, and it was stuck on the bootloader for doomkernel, not in a bootloop just stuck at doomkernel bootloader. I tried to fix this by going to recovery (clockwork mod) and then did a factory reset, wiped the cache and data and the dalvik cache as i saw these online for instructions on how to fix this problem. Still i had the same problem, stuck at bootloader. So i tried somthing different and reinstalled the trueancestors ics rom, and tried to reboot the xperia play, again stuck at bootloader. Im sorry if this was a bit long but I AM LITTRALLY BEGGING FOR SOME HELP! Please make a suggestion as to how i can fix this ASAP. Can it be fixed?Thank you for you Advice it is very much aprecciated. Ive posted this somewhere else in which i couldnt find but i really need help on this, please can anyone help. :crying:

you shouldn't post a like or not like any developer handmake. try back to a stock..

When switching kernels with different partition layout you have to delete data and system partition in fastboot mode.
I'm lazy to type again so here is a link where it is explained already:

You can prevent future problems by wiping data and system partittion from CWM and THEN flash new kernel that have different partittion layout

I havent tried this yet,becuase i need my dad to allow flash tool to work (Parental controls ffs -.-") however i saw the thread and i saw this part saying enter these commands "fastboot erase userdata and fastboot erase system i undestand how to get the command thing open but how do u enter these in, and what i mean is do you just open the command thing and just paste these in or do u have to right click somthing open comand promt here and all the stuff then enter them? Also these steps u listed, everything is fine its just my lack off knowladge for some of these things which i do apologize for
" Fully working steps, that is 100% working:
1.flash ftf with unlocked vendor partition (.62 or .79)
2.flash lupus gb kernel
3.erase system and data from fastboot
4.enter recovery and flash your rom "
Where do you get the unlocked vender partition, and which one is better .62 or .79 and if u could send me a link as your helping me i think ur choice of links for this is more reliable than mine, and again this is greatly appreciated.

" Fully working steps, that is 100% working:
1.flash ftf with unlocked vendor partition (.62 or .79)
2.flash lupus gb kernel
Download file name R800i_4.0.2.A.0.79.ftf from Xperia Play Index - ROM'S, FIRMWARE, KERNEL'S, GUIDE'S, THEMES, MOD'S second post have firmware files
Guide how to use flashtool you can find at [GUIDE][18th Dec][4Noobs] Flashing A FTF File Using Flashtool
Flashing .79 or .62 firmware is necessary if you are planning to use lupus gb or icd/gb kernel - and you only need to do it once.
Flashing kernel is same, but when pressed on lighting icon, choose "fastboot"
3.erase system and data from fastboot
Ok, i made a zip for you. Download it from attachment, unpack to anywhere you like and double-click file named "start". Power off phone, press search and while keeping it pressed, plug in usb. I don't think you need admin rights for that, but:
MAKE SURE YOU HAVE ROM PLACED ON YOUR SD CARD! Just in case, because that program will erase everything from your phone.
You should be able to enter recovery and/or flash your rom/restore your backup.
4.enter recovery and flash your rom "
Also, read some sticky threads, they are there for a reason

Again im really sorry to bother you with this, but what if i dont want to flash the rom, becuase i didnt like it in the first place so i went back to stock, however this method of returning to stock was to flash the R800i_4.0.2.A.0.62_(1253-4437).ftf file. Now what it did was return it to stock rom (AFTER i tried the rom i didnt like) and unrooted the phone, i dont know if it returns the phone to stock firmware, and if the method of the system data wipe thing with the command prompt deleted everything, what can i flash? Little more explaination as to why im asking. Before this boot stuck thing hapenned i had used that same ftf file to return it to stock and unrooted. I re-rooted the phone and then flashed the lupus kernel. Everything was fine. I wanted to flash the doomkernel because like a dum nut i wanted to show off that i could overclock to 2ghz ( if i wanted to) as if alrdy stated before and did so. I think you can only flash zip files from your SD card so the ftf file wont be able to be flashed while on the device. So what do i flash? Should i just flash the rom i dont like and try return it to stock, then flash the ftf .79 firmware again after re-rooting the phone, then flash the doomkernelv14. In short i want to stay with the normal gingerbread 2.3.4 with doomkernelv14. Again i havent tried this yet and also sorry for these long rambly posts, i just want to give you as much info as possible in order for you to help me. Thank you so much for your solution btw much appriciated.:good:

And almost forgot i also want it back to rooted but i can do that myself, i just thought i'd specifiy it just incase its worth anything.

- INFO - Preparing files for flashing
16/033/2013 14:33:53 - INFO - Please connect your device into flashmode.

Any sugessions to what i should do?

Alright i fixed the firmware flash problem and have made it all the way to the the part where you flash your custom rom and the phone should magicly work again. Ive got past the doomlord booting screen, thats good, now im stuck at a black screen, any ideas on whats going on?

K so i fixed all the above problems, by using a different kernel, and repeating all the previous steps, THE XPERIA PLAY IS BACK DUDE THANK YOU( hit the thanks button like 100 times).

Everythings fine at the moment and i dont want to make any more dumb mistakes so im just going to ask if wiping the data and system partitions in CWM still deleted everything. I just recently got all of my apps back and all that good stuff, i just want to know if they will get erased if i do this. My deepest appologies for bothering you with something so minor and selfish.

Sorry another selfish request (Damit) but when ever i flash the doomkernel v14 my wifi gets error, i was wondering if u knew how to fix this, if u dont and have the free time or feel like it, direct me to somone who does?

Yes, if you wipe data and system then EVERYTHING is deleted. All your apps (data) and even android OS itself (system). You'll have to either flash new rom or restore backup after wiping system
Doomkernel need wifi modules to be installed from CWM recovery to have working wifi
I'll attach it

Im wondering about my battery life, because it seems to be draining faster. Im using no frills cpu with the lupus kernel alowing me to overclock to 1.6 ghz. I set my higest on 1613 mhz and lowest on 249mhz using the smartassv2 governer. any idea to whats going on ?

ok...i screw up my xperia play... dunno what to do.
hi guys, been a noob after i fed up with my xperia x8 now i having a xperia play f or 2 years and try to install a custom kernel and roms but i end up brick my phone. it just stuck at logo "xperia free play". it still can enter cwm recovery mode but when i use the method press the arrow thing then plug in the usb cable to pc , it seems my pc did detect my phone but cant show up my memory card in 'my computer' window. The i try to use fastboot & flashtool both can detect my phone after plug in. Here is what i do before brick:
first thing i did on my phone was to upgrade the stock kernel 4.0.2.a.0.42, then i unlock the bootloader, root it, and start download the custom rom without download the requirement kernel. after that, i install CWM using fast boot, put the custom rom to sd card, wipe user data, bla bla bla, then install the custom rom, the next thing i see is the problem i talking about earlier. So i try to using the service update from SCE but it just say im using a modified kernel hence i unable recover it using that method. so, i try to use flash tool x10 (i cant get any working download it keep saying error 404 link, this is the best i have now) when i press the flash it come out red words with error usb ...the thing is my phone cant get detected by my computer.... What to do or it is over? (p/s : i download the flash tool & adb package winrar file & the custom rom i mention is close 2 perfection)
I know is a bit long but I really need help on my phone, i still have a x8 here from my mom and mine is xperia play brick for 3 days now i still cant find a way to solve it. PLEASE HELLLLLLLLLLPPPPPPPPPPPP. THANK YOU FOR THOSE RESPONSE~!

Man i was doing so well before, but im now stuck in a bootloop. I cant enter the recovery menu as the phone just keeps bootlooping. Also with lupus kernel the menu doesnt come up. I just erased the user data and system with ur zip from before and flashed aurora play with lupus v12.5 kernel It worked like everything else. i got more curious so i did the same thing erased user and system data then flashed gin2jellybean with the same kernel.( i followed ur intructions from before on how to flash roms n stuff) Everything worked again. I wanted a new kernel so i flashed extreme kernel r3. phone got stuck in a bootloop. So i erased user data and system data, then flashed and ftf stock rom and then flashed extreme kernel r3. everything was working. I went into titanium backup and uninstalled some system apps and accidently deleted the one that let you see the running services to see available ram. So i cleared data and and system data reflashed ftf stock rom in flashmode ofc, and extreme kernel in fastboot. I got a bootloop, so i tried all the different kernels that i could and i cant get into the menu for recovery. Can you please help me once again, i'll thank every post.

For most part, you are doing it right, but, to solve problem with recovery, you should use "eraser" AFTER you change kernel

Naturaly, it will drain more battery BECAUSE it's overclocked.

I think you should repeat the fastboot process once again, so:
fastboot erase userdata
and fastboot erase system
then just flash the kernel you prefer.
I had exactly the same problem with my play bootlooping after flashing some kernels. and this solved the problem for me :victory:
sorry for my bad English, :crying:
